Seafoam Injector / Intake Cleaner = GOOD STUFF

Over the last few months, my gas mileage has been dropping off horribly. Last monday when I filled up I got 13.8 around town (I've been getting 15 in town and 16.5 on the highway). That was the last straw - I had to do SOMETHING. I picked up a can of seafoam along with some TB cleaner and did a little late spring cleaning. I poured the seafoam into the PCV hose with the engine running like on the directions. On the first application, I poured it very slow (1/3 can), then shut off the engine (again, like the directions said). Five minutes later when I started it up, it blew more smoke than the batmobile. After all the smoke subsided, I gave it another treatment, but poured a little faster so that it was almost stalling out. (again, 1/3 can). After starting up, it BILLOWED smoke for several minutes, but the engine just PURRED after it was finished. It was the smoothest running toyota engine I've ever seen. While I was at it, I gave the MAF a good bath along with the air filter and the TB.

Well, that got me back up to 17.2 on the highway on our trip to the beach (still not satisfied).

While I was down there, I picked up another two cans of seafoam and put both into my tank at 1/2 full (4X stronger than in the directions). I ran this for about 20 miles or so, then filled up at a cheapie station ($1.69 when everywhere else was $1.86) and got back on the interstate to drive home. I filled back up here in Birmingham, and I ended up getting 18.1 on the ride home. Not too bad. I can't wait to see if it goes up even more with Shell in the tank...

Now on startup, instead of having to hold the key for a sec for the engine to fire, it starts right up with ZERO hesitation. The injectors and intake must have been pretty bad (106k and counting)...

If you do the seafoam treatment, I'd recommend SEVERAL cans so you can give the intake a good cleaning along with the injectors.

Andy,

That is encouraging info. However I have a 2nd gen with the 3.0. The PCV valve is not easily accessible. Is there any other way to introduce this stuff to the intake and the injectors?

I absolutely love SEAFOAM! SEAFOAM ROCKS! I have used it in my 3.4, my wifes 3.7 (Jeep), my brothers 4.7, many 22r and 22re motors, etc.

This stuff is absolutely the best motor treatment I know of. Hands down, works better than other products I've tested. I know tons of mechanics who use this stuff, including my cousin who swears by it.

I got my cans at NAPA. On the 3.4L, the PCV is located to the left of the throttle body and down on the top of the head. It's a 1/2" or so hose that attaches to a fitting that is turned 90* horizontal after it comes out of the engine. That fitting is the PCV valve. Pop the hose off when the engine is running and it has TONS of vacuum to suck in the Seafoam. Give me a few minutes and I'll go take a pic of it...

Also be prepared to replace the plugs in your vehicle approx. 1 to 2 weeks AFTER you have the procedure done, all the crap the gets burnt out of the system has a tendency to foul the plugs killing your milage and performance.

I have no idea if it's true or not, kinda' makes sense, so I figured I'd pass it on.

Hey Andy? How long after the treatment did you start noticing an improvement in how the engine runs? Was it really as quick as _right now_? I ask 'cause I just got done doing mine, but didn't get the smoke cloud... hmm...
